4.5mm Wall Steel Core Hidden Clip 100x50mm WPC Tube Profile

This premium 100x50mm WPC Tube Profile is engineered specifically for modern architectural facades, exterior sunshade louvers, and high-span spatial partitions. Manufactured with an upgraded 4.5mm wall thickness via high-density co-extrusion technology, this profile significantly enhances sectional rigidity and impact resistance compared to standard hollow slats.

To satisfy demanding structural requirements in high wind-load or suspended installations, the internal chamber is designed to seamlessly integrate an internal steel core (galvanized steel tube), uniting structural strength with the natural warmth of timber aesthetics. The specialized hidden clip (304 stainless steel fastener) mounting system completely eliminates surface-exposed screws, providing architects and contractors with a sleek, screw-free finish for high-end commercial and residential cladding projects.

• 4.5mm Wall Structural Integrity: Compared to common thin-walled profiles, the 4.5mm wall engineering effectively absorbs internal stress caused by thermal expansion and contraction, preventing long-term warping, twisting, or bending.
• Steel Core Composite Load-Bearing Performance: For high-altitude louvers or unsupported vertical screens, inserting a galvanized steel core transfers structural gravity and wind pressures to the inner metal framework, allowing the outer WPC tube to act as a durable, weather-resistant decorative shell.
• Hidden Clip Fast Installation: Custom-engineered 304 stainless steel hidden clip components match the side grooves of the profile, eliminating face-drilling and accelerating installation by up to 40% while preserving a clean aesthetic and allowing non-destructive profile removal.
• Extreme Weatherability & Low Maintenance: Engineered for harsh outdoor climates, the high-density WPC tube operates reliably in temperatures from -40°C to +60°C, with ultra-low water absorption that resists mold and salt-spray corrosion.

This combination addresses structural mechanics and thermodynamic behavior simultaneously. The 4.5mm wall specification gives the 100x50mm WPC tube exceptional inherent rigidity for standard wall cladding. However, when spans exceed 1.5 meters in exterior sunshade louvers or high wind-pressure zones, inserting an internal steel core ensures that flexural and wind loads are borne by the steel section. This hybrid design guarantees that the WPC tube profile will not bow, creep, or sag even under intense heat and wind exposure.

It offers outstanding structural security. The hidden clip engineered for the 100x50mm WPC tube profile is manufactured from 1.2mm thick 304 stainless steel, yielding a pull-out force rating exceeding 800N per connection point. The hidden clip forms a mechanical interlock within the side channels of the WPC tube, successfully resisting negative wind-load suction forces while keeping the facade free of visible fasteners.

The 100x50mm WPC tube features a classic 2:1 golden aspect ratio. At viewing distances of 5 to 15 meters, it provides greater visual substance than smaller profiles without appearing overly heavy. Enhanced by a 4.5mm wall, optional steel core reinforcement, and an efficient hidden clip mounting system, this profile stands out as the universal benchmark specification for luxury villa facades and commercial cladding projects.
